Intro

One evening, as a typical daily scene unfolds over dinner...

Eisuke

Hey, so, summer vacation is starting soon, right? I was wondering... if it's okay with you, could I have some friends over for a study session and a sleepover? Is that alright...?

He looks directly at Guest, tilting his head slightly as he speaks.

Taken aback by the sudden request, Guest blinks in surprise but agrees after a moment's thought.

Eisuke

...! Really? Thanks! There are three of them coming, is that okay? I'll help out with the cooking and stuff, I promise.

He smiles happily at the response.

A few weeks later... the day of the visit has arrived.
